I tried this link and the player started playing successfully.
Can you show us a print screen with the error you are getting?

Sorry for the last comment, I tried with the wrong code.
I got your error, you did a nicejob identifying the colon pattern, this makes the solution very trivial.
I could make a PR but the owner of this repository doesn't work with this bot anymore, so just change this in your code:
In the file audiocontroller.py add this line of code in search_youtube function:

The problem might be in the way this function calls the ydl.extract_info method, but it's easier to fix this particular error.
If you are looking for a more stable discord music bot you can try this one: Vulkan

Just an alternative: my fork also has this issue fixed.
